22. In 12 weeks Felipé earns earns $4,500 doing yard work. He earns the same amount each week. Let m stand for the amount earned each week. How much more does Felipé make in 1 week. 23. Abel has 3,330 toothpicks. He wants to use them all to make a floor mat with 18 equal rows. Use the bar graph to write a division expression. Then solve the equation to find how many toothpicks Abel should use in each row.

plz yuo

step-by-step explanation:

let's call the solutions x₁ = (5 - 2√7)/3 and x₂ = (5 + 2√7)/3

then the equation is (x-x₁)(x-x₂) = 0

if you fill that in you get a lot of numbers which you can recognize as ax²+bx+c=0.

step-by-step explanation:

you can see that a=1 (there is just an x²)

b = (-5 -2√7 + 2√7 - 5)/3 = -10/3

c = -2√7)/3 ) * (-5+2√7)/3) = -1/3

so your answer is 3x^2 – 10x – 1 = 0

he has 140 chickens because he has 10 times more chickens than ducks and he has 14 ducks so 14*10=140

the ratios are reciprocals im positive

step-by-step explanation:

they are all positive numbers so it wouldn't be the other ones
